Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137956, here are decompositions:
- 23 + 137933 = 137956
- 29 + 137927 = 137956
- 47 + 137909 = 137956
- 83 + 137873 = 137956
- 89 + 137867 = 137956
- 107 + 137849 = 137956
- 179 + 137777 = 137956
- 233 + 137723 = 137956
Showing the first eight; more decompositions exist.
